Embodiment
See Fig. 1, Fig. 2, Fig. 3, coke oven coal-charging and when the discharging of the coke two-in-one earth station dust removing system comprise following plurality of processes:
1) discharge of the coke when operation, by coke guide 6 with dust gathering arrester 12, utilize the negative-pressure operation of system, flue dust collecting in the time of will the discharging of the coke, be sent in the control of dust main 7 that leads to ground station for dust removal by interface valve, flue dust passes through sack cleaner 4 again through giving fly-ash separator 5 earlier, enters atmosphere after the processing.
When 2) coalingging operation, the smoke elimination car 11 that utilizes furnace roof to be provided with, from air suction opening (hole of coalingging) 13 flue dust collectings of releasing out, by being burnt and purified in the combustion chamber, ooze the freezing air cooling again, by interface valve flue gas is sent in the control of dust main 7 that coke discharging and dedusting uses, arrives the sack cleaner 4 of ground station for dust removal again by giving fly-ash separator 5 earlier equally, enter atmosphere after the dust removal process.
